Eyes on the pavement

This is the first time I've seen the Look sign with the arrow on the pavement in Canada.

They are common in London, but I thought that was to warn those many UK tourists from the large majority of countries where they drive on the right.

I wonder why we need these here. Do we really have that many visitors from countries that drive on the right?

From the UK, Japan, Barbados, Guyana, Zimbabwe and Bermuda? I doubt it. Besides, why didn't these people need the Look signs before?

This sign has been painted at the four corners of Broadway and Clark, but the others are already worn off. Guess the green paint was a little too green. It doesn't last. But that's ok. We probably didn't need these signs in the first place. Just like we didn't need the green-painted crosswalks.
